+# DBAL Integration Guide
+
+## Overview
+
+The MetaBuilder application now has DBAL (Database Abstraction Layer) wired up and ready for use. DBAL provides a unified interface for database operations with support for multiple adapters, ACL, audit logging, and more.
+
+## Architecture
+
+### Current Setup
+
+- **DBAL Layer**: Located in `dbal/ts/src/` - provides the core abstraction with Prisma adapter support
+- **Server-Side Integration**: `src/lib/database-dbal.server.ts` - server-only module that initializes and exports DBAL operations
+- **Database Class**: `src/lib/database.ts` - maintains backward compatibility with existing code using Prisma directly
+- **API Routes**: Demonstrate DBAL usage (e.g., `app/api/users/route.ts`)
+
+### Why Two Approaches?
+
+1. **Database Class (Prisma Direct)**: Used by client components and existing code for backward compatibility
+2. **DBAL (Server-Only)**: Used in API routes and server components for:
+   - Multi-adapter support
+   - ACL/permission checking
+   - Audit logging
+   - WebSocket bridge capability
+
+## Using DBAL in Your Code
+
+### ✅ Server-Side Usage (API Routes, Server Components, Server Actions)
+
+```typescript
+import { dbalGetUsers, dbalAddUser, initializeDBAL } from '@/lib/database-dbal.server'
+
+// In an API route
+export async function GET() {
+  await initializeDBAL()
+  const users = await dbalGetUsers()
+  return NextResponse.json({ users })
+}
+
+// In a Server Action
+'use server'
+export async function createUser(formData: FormData) {
+  await initializeDBAL()
+  const user = await dbalAddUser({
+    username: formData.get('username'),
+    email: formData.get('email'),
+    role: 'user'
+  })
+  return user
+}
+```
+
+### ❌ Client-Side (Will Not Work)
+
+```typescript
+// DON'T DO THIS - will cause build errors
+import { dbalGetUsers } from '@/lib/database-dbal.server' // ❌ server-only module
+
+function MyComponent() {
+  const users = await dbalGetUsers() // ❌ can't use DBAL on client
+}
+```
+
+For client-side code, use:
+- The existing `Database` class (which uses Prisma directly)
+- API routes that use DBAL internally
+- Server Components with DBAL
+
+## DBAL Features
+
+### 1. Multi-Adapter Support
+```typescript
+const config = {
+  adapter: 'prisma', // or 'sqlite', 'mongodb' (when implemented)
+  database: { url: process.env.DATABASE_URL }
+}
+```
+
+### 2. ACL Integration
+DBAL includes built-in access control:
+```typescript
+const config = {
+  auth: {
+    user: currentUser,
+    session: currentSession
+  },
+  security: {
+    sandbox: 'strict', // or 'permissive', 'disabled'
+    enableAuditLog: true
+  }
+}
+```
+
+### 3. Validation
+All DBAL operations include automatic validation:
+```typescript
+// Automatic validation of user data
+await dbal.users.create({
+  username: 'john', // validated
+  email: 'invalid',  // throws validation error
+})
+```
+
+### 4. Error Handling
+DBAL provides consistent error types:
+```typescript
+try {
+  await dbal.users.create(userData)
+} catch (error) {
+  if (error instanceof DBALError) {
+    if (error.code === 409) {
+      // Handle conflict (duplicate username/email)
+    }
+  }
+}
+```
+
+## Migration Path
+
+### Current State
+- ✅ DBAL is initialized and working
+- ✅ Prisma adapter is configured  
+- ✅ Server-side API routes can use DBAL
+- ⏳ Database class still uses Prisma directly (backward compatibility)
+
+### Future Enhancements
+1. Gradually migrate Database class methods to use DBAL internally
+2. Add support for SQLite and MongoDB adapters
+3. Implement full audit logging
+4. Add WebSocket bridge for C++ daemon communication
+
+## Testing DBAL
+
+Test the DBAL integration using the API route:
+
+```bash
+# Start the dev server
+npm run dev
+
+# Test the DBAL-powered users endpoint
+curl http://localhost:3000/api/users
+```
+
+Expected response:
+```json
+{
+  "users": [...],
+  "source": "DBAL"
+}
+```
+
+## Benefits of DBAL
+
+1. **Abstraction**: Switch database backends without changing application code
+2. **Type Safety**: Full TypeScript support with validation
+3. **Security**: Built-in ACL, sandboxing, and audit logging
+4. **Performance**: Connection pooling, query timeouts, caching support
+5. **Testing**: Easy to mock and test with different adapters
+6. **Multi-tenancy**: Built-in tenant isolation and quota management
+
+## Next Steps
+
+To fully adopt DBAL throughout the codebase:
+
+1. Create API routes for all database operations
+2. Update client components to call API routes instead of using Database class directly
+3. Migrate server components to use DBAL
+4. Eventually refactor Database class to use DBAL internally
+
+This gradual approach ensures backward compatibility while enabling new code to leverage DBAL's advanced features.
